* Bump minor version * bump benchmarks compat * add a skeletal changelog * `InitContext`, part 3 - Introduce `InitContext` (#981) * Implement InitContext * Fix loading order of modules; move `prefix(::Model)` to model.jl * Add tests for InitContext behaviour * inline `rand(::Distributions.Uniform)` Note that, apart from being simpler code, Distributions.Uniform also doesn't allow the lower and upper bounds to be exactly equal (but we might like to keep that option open in DynamicPPL, e.g. if the user wants to initialise all values to the same value in linked space). * Document * Add a test to check that `init!!` doesn't change linking * Fix `push!` for VarNamedVector This should have been changed in #940, but slipped through as the file wasn't listed as one of the changed files. * Add some line breaks Co-authored-by: Markus Hauru <markus@mhauru.org> * Add the option of no fallback for ParamsInit * Improve docstrings * typo * `p.default` -> `p.fallback` * Rename `{Prior,Uniform,Params}Init` -> `InitFrom{Prior,Uniform,Params}` --------- Co-authored-by: Markus Hauru <markus@mhauru.org> * use `varname_leaves` from AbstractPPL instead (#1030) * use `varname_leaves` from AbstractPPL instead * add changelog entry * fix import * tidy occurrences of varname_leaves as well (#1031) * `InitContext`, part 4 - Use `init!!` to replace `evaluate_and_sample!!`, `predict`, `returned`, and `initialize_values` (#984) * Replace `evaluate_and_sample!!` -> `init!!` * Use `ParamsInit` for `predict`; remove `setval_and_resample!` and friends * Use `init!!` for initialisation * Paper over the `Sampling->Init` context stack (pending removal of SamplingContext) * Remove SamplingContext from JETExt to avoid triggering `Sampling->Init` pathway * Remove `predict` on vector of VarInfo * Fix some tests * Remove duplicated test * Simplify context testing * Rename FooInit -> InitFromFoo * Fix JETExt * Fix JETExt properly * Fix tests * Improve comments * Remove duplicated tests * Docstring improvements Co-authored-by: Markus Hauru <markus@mhauru.org> * Concretise `chain_sample_to_varname_dict` using chain value type * Clarify testset name * Re-add comment that shouldn't have vanished * Fix stale Requires dep * Fix default_varinfo/initialisation for odd models * Add comment to src/sampler.jl Co-authored-by: Markus Hauru <markus@mhauru.org> --------- Co-authored-by: Markus Hauru <markus@mhauru.org> * `InitContext`, part 5 - Remove `SamplingContext`, `SampleFrom{Prior,Uniform}`, `{tilde_,}assume` (#985) * Remove `SamplingContext` for good * Remove `tilde_assume` as well * Split up tilde_observe!! for Distribution / Submodel * Tidy up tilde-pipeline methods and docstrings * Fix tests * fix ambiguity * Add changelog * Update HISTORY.md Co-authored-by: Markus Hauru <markus@mhauru.org> --------- Co-authored-by: Markus Hauru <markus@mhauru.org> * fix missing import * Shuffle context code around and remove dead code (#1050) * Delete the `"del"` flag (#1058) * Delete del * Fix a typo * Add HISTORY entry about del * Fixes for Turing 0.41 (#1057) * setleafcontext(model, ctx) and various other fixes * fix a bug * Add warning for `initial_parameters=...` * Remove `resume_from` and `default_chain_type` (#1061) * Remove resume_from * Format * Fix test * remove initial_params warning * Allow more flexible `initial_params` (#1064) * Enable NamedTuple/Dict initialisation * Add more tests * fix include_all kwarg for predict, improve perf (#1068) * Fix `include_all` for predict * Fix include_all for predict, some perf improvements * Replace `Metadata.flags` with `Metadata.trans` (#1060) * Replace Medata.flags with Metadata.trans * Fix a bug * Fix a typo * Fix two bugs * Rename trans to is_transformed * Rename islinked to is_transformed, remove duplication * Change pointwise_logdensities default key type to VarName (#1071) * Change pointwise_logdensities default key type to VarName * Fix a doctest * Fix DynamicPPL / MCMCChains methods (#1076) * Reimplement pointwise_logdensities (almost completely) * Move logjoint, logprior, ... as well * Fix imports, etc * Remove tests that are failing (yes I learnt this from Claude) * Changelog * logpdf * fix docstrings * allow dict output * changelog * fix some comments * fix tests * Fix more imports * Remove stray n Co-authored-by: Markus Hauru <markus@mhauru.org> * Expand `logprior`, `loglikelihood`, and `logjoint` docstrings --------- Co-authored-by: Markus Hauru <markus@mhauru.org> * Remove `Sampler` and its interface (#1037) * Remove `Sampler` and `initialstep` * Actually just remove the entire file * forgot one function * Move sampling test utils to Turing as well * Update changelog to correctly reflect changes * [skip ci] Make changelog headings more consistent --------- Co-authored-by: Markus Hauru <markus@mhauru.org>
